HYDRAULIC-POWER SYSTEM.

Specification of Letters Patent. t t d Sept, 1910;,

Application filed-September 8, 1909. Serial No. 516,793.

To. all whom it may concern: Be it known that I, THOMAS A. MACDON: ALB, a subject-"of the King of Great Britain, and resident of Clifton, in the cbunt y Pas'saic and State 'of New Jersey, have invented certain new and useful Improvemeans-byiwhich the ceaseless beating of the;

of the water ments in Hydraulic-Power Systems, of which the followin is a specification.

My invention re ates to'improvements for utilizing the waves and tides of the ocean or other large bodies of water, and it .con-' sistsv in the combinations, constructions and arrangements of-parts, herein described and claimed.

object. of myinvention is to provide waves upon the shore maybe made to charge a reservoir dis ed above the normal-level thence back into the main body of water.

' -A further object of my invention is tofor elevate in'g. the-water from the large bod provide a. novel for-m of device of water into the firsll l amed reservoir an for auto "35. features will be articularlypointedout in theappended claims. i

riiatically adjusting the height of the elevating apparatus in accordance with the rise of the water in the reservoir. 1

A further object of my inventionis .to'

' provide means for preventing the-inflowof Waterfrom the ocean or main body'ofwater into the; lower reservoir.

Other objects and advantages will a p iear in the following specification, and the novel MylIIVGHtlOIX -is illustrated in the-accom- 4'5. I; gat'e slong thejline3-3 of Fig. 1, Fig. 4-

' inclined sides rr'angement of. my hydraulic Fig. '2 is a longitudinal secthrough the tail race above low waterr In the figure, I have in i-' ceted this first elevated pond at A, while the second pond which is at' a. lower level, is

shown at B. While I have shown these two ponds as being separated from" the "main body by a strip of land, C, it will be understood that these ponds or reservoirs maybe at a considerable distance from the ocean and be 'conne'ctedtherewith by channelsot greater extentthan the cuts in-the strips- ;shownin the drawing.

"On the shore D,, oppo's1te the reservoir A,

I installa water. elevating device, which. I-

have denoted in general by E, which designed 'to elevatethe water with great ra idr ity. The construction ofthi's water elevatg device is nost clearly shown in Figs, 2,

'5, and 6.

Referring-particularly to Fig. 2, it will be seen that on the beach D. at the edge'of-the main"body of water-F, I drive the-"pilesgG which holdthe standard HQthe oppositeside- :being provided with similar piles G5 and the standard H as shown in Fig. .5 Between 011 the rods Kand Kfa'plurality of inclined chutes L, Leand L These chutes, are wider at their lower. ends, and taper toward their.

= They are provided with the v m .(as shown in thefigures). The bottom-of. each chute is provided, with a series of hinged strips Owhich are pivoted upper ends.

normal position of these strips is that shown in 2, in which thereisa curvedchannel' I; These strips are limited by means. of in slotsS in the sides our feet may intervene bepins B'whichpla A space of about tween the strips as lifted has ten seconds to rundown and out- :between each wave, since about six waves tofthe minute roll in on the shore.

.85 the. two standards II- is pivotally inountedat-their centers so as to 'swing into-the position shown in dottedhnes 'ln'Flg. The

the water thus .pertiiilly,

and I which are. secured on either side to' the abutments V andV". 'Secured to the bottom of the chutesis a retaining member X which is in close contact with a retaining wall W.

At Z I have shown the power devices, which are turbines such as that shown at 1 i in Fig. 3. Of course there may be num.-

.Each ,turbine is provided with a which may be raised or lowered to bring the turbine into operation., The bottom of the her of these turbines, and they are preferably connected to a common power shaft 2. gate .3,

turbine rests upon standards 4:, so as to provide a space 5 beneath the. turbines to per- 'mitthewater meow out therethrough. 'A

power house Q ma be conveniently located near the turbines or generating electricity.

The lower reservoir B has con'nni'inicating with it a'tail-race 6, which is approximately on a level with the water Qf .tl18 ocean or main body. This tail race has at, its outer end a gate 7 provided with a float 8, on one end, adapted to rise and fall with the rise and fall of the water F. A stop member 9 limits the movement of this ate 7 Around the end of the tail; race, 'whereit emptiestintothe main body of water, I construct a break-water, 10 (as'shown in Fig. 1). In order to concentrate the forceof the waves, I provide the converging extensions Y and Y which join the lower ends of the outer chutes.

From the foregoing description of the va-' rious thereo may be readily understood.

As the waves come in,-they are concen-' trated bythe converging members Y and Y, and their force is augmented in the in- 'clined chutes L and L and L. The water,

with the momentum which it has, acquired,

rushes up these inclined chutes and pours into thereservoir A. In order to revent the back flow ofthe water which ails to here 0 toswingup into t in dotted lines'zthus'openmg these small trap coming wave;

reach the reservoir from interfering With the oncoming wave, I have provided the swinging members 0 .already explained. The'returning water rushes down through the slots Fund in so doing causes the meme position shown and "allowing the water to pass doors, p through underneath the device, from whence it may flow to the main-body, thus shunting the water around, orrather upder the on- As the water in the upper reservoir A rises, the fioatnarries the upper end of the inclined chutes, higher. he

Farts of the device, the, operation ing the latter in accordance with the how ing t water of the reservoir A being prevented from flowing out by the close contact of the relat-iyely sliding members X and W. Of course theremay beas many of these water elevating devices as desired, and the water keeps flowing in to the upper reservoir, constantl This upper reservoir may be of consi erable extent, and preferably ens-4 braces many acres.- The water from the reservo r may be used as desired, oneach or all of the turbines, andthe power thus derived 'may 'be used for running dynamos, or other power generators. .As the water flows into the lower reservoir, the level-of the Water, of courtc, rises, but this lower reservoir is also designed to be of such extent that the rise of the water is slow.

. As the tide begins to rise, in the main body of water, the gate 7 rises with" it, being lifted by the float 8, so'that no water from the ocean can flow in through the tail race, -1nto .the lower reservoir.

Now when the tide recedes, the gate 7 lowers into the position shown in dotted. lines in Fig. 4', and the waterin the reservoir having accumulated to a higher level than the main body of water at low tide flows out through the tail race, and into the larger body.

The waves in the larger body'inight interfere with the outflow of water through the tail race, but in order to prevent this, I have arranged a breakwater 10, which prevents the wavesfrom. doing any damage to the gate 7, and leaves a comparatively still body of water 11 surrounding the end of, the tail race. p

I have spoken of natural reservoirs, but 1t will be understood that artificial reservoirs power desired thereafter may be obtainedat ractically no expense, except from the or din-ary wear of the operating parts. v I claim: 1. In a hydraulic power system, the' conibination with a main body of water, of an upper reservoir disposed above the level of said main body of water, means for receiving .water from said .main body of water, and causing the projection 0f'thB- Wate1 of the waves into said upper reservoir, a float in said upper reservoir connected wlth said water raising means for elevating and lowerdepth of the water in the upper reservoir, :1- lower reservoir, power devices arranged to be'op might be economically made, when the said main body of water Za'nd having an automatic gate for permitting the flow of water from said lower reservoir into said main body? -'and for prevent ng a reverse discharge end of the tail race.

interference of an oncoming wave with a receding wave. 7
